Abstract

Objective: To evaluate factors associated with the Severity of RSV Bronchiolitis in Children at Thai Binh Pediatric Hospital.  Subjects and Methods: A prospective descriptive study was conducted on 300 children aged ≤2 years, diagnosed with RSV-positive bronchiolitis at Thai Binh Pediatric Hospital from May 1, 2024, to April 30, 2025. Results: The mean age was 6.7 ± 6.02 months, with a male-to-female ratio of 2.2:1. Most patients had mild disease (59%), while 26% had moderate and 15% had severe disease. Moderate and severe cases were more common in children under 2 months of age (15.3%). Infants ≤2 months had a significantly higher risk of mild to severe disease compared to those >2 months (OR = 3.5, p < 0.05). Preterm infants had a higher risk of moderate to severe disease than full-term infants (OR = 2.6, p < 0.05). Children with radiographic lung lesions had a higher risk of severe disease than those without lesions (OR = 3.5, p < 0.05). Children with SpO₂ < 95% had a higher risk of severe disease than those with SpO₂ ≥ 95% (OR = 5.4, p < 0.05). Conclusion: Significant prognostic factors for disease severity in pediatric RSV bronchiolitis include age, prematurity, radiographic lung involvement, and oxygen saturation below 95%.
